I’m following the guide here, trying to get the sample project working on my device. After following all their steps, (connecting to my watch device and creating a certificate profile) when I try to run it on the device, I get the following error:

“The application installation on the device has failed due to a signature error! (error code : -12)

You need an appropriate certificate profile, which can be created or activated in the Certificate Manager. Do you want to open the Certificate Manager?”

I thought I did that already by following this.

Not sure what could be going wrong. When I try to run it on the emulator it works perfectly.

Any insight into this would be greatly appreciated.
